BlackTHUNDER Reveals a Massive Filament around a Compact AGN at
Giulia Tozzi, Hannah Übler, Eleonora Parlanti +27
Despite the growing number of compact active galactic nuclei (AGN) at discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
Little Red and Blue Dots: AGN-excited narrow lines, Lyman- emission, and resemblance to standard quasars
Sophia Geris, Roberto Maiolino, Xihan Ji +35
We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at , identified by JWST in the GOODS fields. While both categories are selected to ha…
JADES: the mass-metallicity relation at . New calibrations, extremely metal-poor galaxies, and chemical diversity
Yuki Isobe, Mirko Curti, Roberto Maiolino +28
We present gas-phase metallicities of star-forming galaxies at -10 with deep JWST/NIRSpec spectra from the JADES full data release, Dark Horse, and OASIS programmes. We stack…
The Way We Tally Becomes the Tale: the Impact of Selection Strategies on the Inferred Evolution of Little Red Dots Across Cosmic Time
Pierluigi Rinaldi, Kevin Hainline, Francesco D'Eugenio +27
Little Red Dots (LRDs) have emerged as a key population linked to early black hole growth, yet photometric selections have predominantly targeted only the most extreme red systems,…
Holes in the BH? AGN signatures in the FUV spectrum of a black-hole dominated Little Red Dot at
Xihan Ji, Gabriele Pezzulli, Francesco D'Eugenio +15
It has been suggested that "Little Red Dots" (LRDs) might be accreting black holes enshrouded by dense gas in a nearly closed geometry, which completely covers the central black ho…
Little Red and Blue Dots: simply stratified Broad Line Regions
J. Scholtz, F. D'Eugenio, R. Maiolino +14
It has been claimed that a fraction of the so-called Little Red Dots (LRDs) are characterised by exponential broad line profiles, which have been ascribed to broadening from electr…
The Little Blue and Red Dots Rosetta Stones: Non-Gaussian broad lines, hot dust, and X-ray weakness
M. Brazzini, F. D'Eugenio, R. Maiolino +31
The population of Active Galactic Nuclei (AGN) newly discovered by the James Webb Space Telescope (JWST) exhibits peculiar properties that distinguish it from both local type I AGN…
Mergers lighting the early Universe: modest star formation enhancement without evidence for AGN or Ly triggering
Dávid Puskás, Sandro Tacchella, Charlotte Simmonds +16
Galaxy mergers and interactions are often invoked to explain enhanced star formation, black hole growth, and mass build-up of galaxies at later cosmic times, but their effect is po…
JADES Dark Horse: demonstrating high-multiplex observations with JWST/NIRSpec dense-shutter spectroscopy in the JADES Origins Field
Francesco D'Eugenio, Erica J. Nelson, Daniel J. Eisenstein +40
We present JWST/NIRSpec dense-shutter spectroscopy (DSS). This novel observing strategy with the NIRSpec/MSA deliberately permits a high number of controlled spectral overlaps to r…
Black Holes in the Shadow: The Missing High-Ionization Lines in the Earliest JWST AGNs
Greta Zucchi, Xihan Ji, Piero Madau +5
Observations with the James Webb Space Telescope (JWST) have uncovered a substantial population of high-redshift, broad-line active galactic nuclei (AGNs), whose properties challen…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
BlackTHUNDER: Shedding light on a dormant and extreme little red dot at z=8.50
Gareth C. Jones, Hannah Übler, Roberto Maiolino +17
Recent photometric surveys with JWST have revealed a significant population of mysterious objects with red colours, compact morphologies, frequent signs of active galactic nucleus…
JADES: the chemical enrichment pattern of distant galaxies -- enhancement, silicon depletion, and iron enhancement
Yuki Isobe, Roberto Maiolino, Xihan Ji +26
We present gas-phase abundances of carbon (C), -elements (O, Ne, Si, and Ar) and iron (Fe) obtained from stacked spectra of high- star-forming galaxies with the deep Near Inf…
JADES and BlackTHUNDER: rest-frame Balmer-line absorption and the local environment in a Little Red Dot at z = 5
Francesco D'Eugenio, Ignas Juodžbalis, Xihan Ji +32
We present a broad-line AGN at z=5.077, observed with both NIRSpec/MSA and NIRSpec/IFU by the JADES and BlackTHUNDER surveys. The target exhibits all the hallmark features of a 'Li…
A big red dot at cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +22
We report the discovery of a little red dot (LRD), dubbed BiRD ('big red dot'), at in the field around the quasar SDSSJ1030+0524. Using NIRCam images, we identifie…
